So basically whenever I click a button the counter will go up and save it to a mysql database. Heres what I have so far but it doesn't echo the number it gives no errors.
try {
$db = new PDO('mysql:host=localhost;dbname=mydatabse;charset=utf8', 'myusername', 'password');
} catch(Exception $e) {
die('Error : '.$e->getMessage());
}
if( isset($_POST['clicks']) ) {
$sql = "UPDATE clicks SET clicks=clicks+1";
$result - $db->query($sql);
}
$row = $db->query('SELECT * FROM clicks');
while ($data = $row->fetch()) {
echo $data["clicks"];
}
I don't know if the clicking part works either due to nothing ebing echoed...
The sql table is: Big int 20 clicks
fix this:
$result - $db->query($sql);
to this:
$result = $db->query($sql);
Maybe you dont reload the page onclick so echo does not work
Try adding this instead of your echo and see if it works:
$clicks = $data["clicks"];
echo "<script language='JavaScript' type='text/javascript'>";
echo "alert('$clicks');";
echo "</script>";

I am new to...well everything. Bear with me.
I have a website that has a textbox for user input ( a code they receive). When they submit, it sends the code to a PHP file, which then checks the code against a database. If it matches the winner code, it redirects the user to a specific page. Losers, are redirected to a loser page.
That works!
However, I'm now trying to redirect users to a third page, if their code matches a different table of codes, but I can't figure out the if else statements. Can anyone help a poor doodle like myself? Thanks!
Here's what I got:
// Connect to your MySQL database
$dbhst = "localhost";
$dbnme = "blah";
$bdusr = "blaaah";
$dbpws = "blahblahblacksheep";
// Using PDO to connect
$conn = new PDO('mysql:host='.$dbhst.';dbname='.$dbnme, $bdusr, $dbpws);
// Getting variables
$answer = $_POST['answer'];
$questionID = $_POST['questionID'];
// Comparing answers
try {
$stmt = $conn->prepare("SELECT * FROM Winners WHERE Winners='" . $answer . "' LIMIT 0,1");
$stmt->execute();
$result = $stmt->fetchAll();
if ( count($result) ) {
foreach($result as $row) {
// echo 'Congrats, you've entered a correct code';
header("Location: https://get-a-brik.myshopify.com/pages/8522");
}
} else {
// echo 'Your code did not win. Please try again.';
header("Location: https://get-a-brik.myshopify.com/pages/5551");
exit;
}
} catch(PDOException $e) {
echo 'ERROR: ' . $e->getMessage();
}
?>
You can use an if ... else if ... else statement:
if (... user is winner ...) {
header("Location: https://get-a-brik.myshopify.com/pages/8522");
} else if (... user is looser ...) {
header("Location: https://get-a-brik.myshopify.com/pages/5551");
} else {
header("Location: winner page");
}
I wrote this code to comment system on my webpage. But i want to keep showing all data on web page while another people do comment and see another people's comment
include 'connection.php';
$con1= new connection();
$db=$con1-> open();
$qry= "INSERT INTO post (content) VALUES ('".$_POST["commentEntered"]."')";
$db->exec($qry);
if(isset($_POST['Submit'])) {
if ($con1->query($qry) === TRUE) {
echo "Your Comment Successfull Submited";
} else {
echo "Error: " . $qry . "<br>" . $con1->error;
}
$sql = 'SELECT * FROM post';
$q = $db->query($sql);
$q->setFetchMode(PDO::FETCH_ASSOC);
$con1->close();
}
if ($_POST)
echo "<h2> Your Comment Successfully Submitted</h2> <br> ".$_POST['commentEntered']."<br>";
}
?>
after your select, inside your if($_POST) write this
while ($row = $q->fetch()) {
foreach($row as $key=>$val){
if (!is_numeric($key)) echo "<p>$key=>$val</p>";
}
}
EDIT i'm not 100% sure you can close the connection and still do a ->fetch, (I think you can but i've never tried it) so you may have to move your connection close after this (but I think you'll be alright), also I am not sure if setFetchMode will return duplicate numbered keys or not so as a precaution I have filtered for them you may not need to
im having a simple mysql/php problem. so i am adding in Image titles for my website, and the code is displayed below. It works, but when you dont put a image, it shows up as blank. I need it to show up as 'No image title' (bc i will use this for image description to). It basically gets the image name, then takes the title from that row.
So how do i do it? :/ im still very new to PHP.
<?php
if (isset($imgtitleset))
{
$sql = "SELECT image_title FROM images WHERE image_name = '$image_main'";
$result = mysql_query ($sql);
while ($row = mysql_fetch_array($result))
{
$imgtitle= $row["image_title"];
echo "$imgtitle";
}
}
else {
echo 'no image title';
}
?>
Change the while loop like so:
while ($row = mysql_fetch_array($result)) {
$imgtitle= $row["image_title"];
if($imgtitle != '') {
echo $imgtitle;
} else {
echo 'no image title';
}
}
Also, I'm not sure what the $imgtitleset variable is for, but you can probably get rid of the if statement checking to see whether it's set.
Edit: the whole thing should probably look like this:
<?php
$sql = "SELECT image_title FROM images WHERE image_name = '$image_main'";
$result = mysql_query ($sql);
while ($row = mysql_fetch_array($result)) {
$imgtitle= $row["image_title"];
if($imgtitle != '') {
echo $imgtitle;
} else {
echo 'no image title';
}
}
?>
This all depends on what $imgtitleset is equal to. It is clearly set against something:
while ($row = mysql_fetch_array($result)) {
$imgtitle = $row["image_title"];
if (isset($imgtitle))
echo "$imgtitle";
else
echo 'no image title';
}
This would mean if nothing was found in the database then it will echo the no image title. However like I said, this could depend on what $imgtitleset is, maybe post the code for that?
If you only expect the select to return a single row, then use if rather than while and return the error on else:
<?php
if (isset($imgtitleset))
{
$sql = "SELECT image_title FROM images WHERE image_name = '$image_main'";
$result = mysql_query ($sql);
if ($row = mysql_fetch_array($result))
{
$imgtitle= $row["image_title"];
echo "$imgtitle";
}
else {
echo 'no image title';
}
}
?>
How could I have my database connection information at the top of my page but have the query separate from the code but still related so that I could have the print or echo displaying the retrieved images in a Div that I could place anywhere on my site?
<?php
$db = new PDO('mysql:host=host;dbname=dbname;charset=UTF-8', 'username', 'password');
$q = "SELECT badge1 FROM user_badges WHERE username='{$_SESSION['username']}' LIMIT 1";
$r = mysql_query($q);
$row = mysql_fetch_assoc($r);
$badge1 = $row['badge1'];
if($badge1 == "unlocked") {
print "image if user has unlocked the badge";
} else {
print "image if user hasn't unlocked the badge";
}
?>
I would like to have the above if and else statements placed in a div so I could position the images printed from the query anywhere on my site. Is this possible?
A couple of ways. Here is one example:
<?php
$db = new PDO('mysql:host=host;dbname=dbname;charset=UTF-8', 'username', 'password');
$q = "SELECT badge1 FROM user_badges WHERE username='{$_SESSION['username']}' LIMIT 1";
$r = mysql_query($q);
$row = mysql_fetch_assoc($r);
$badge1 = $row['badge1'];
?>
//Break out of PHP and add any HTML elements you want
<div id="whatever">
<?php
if($badge1 == "unlocked") {
print "image if user has unlocked the badge";
} else {
print "image if user hasn't unlocked the badge";
}
?>
</div>
p.s. Check your PDO. It's mixed with old MySQL_ stuff
I have a php which would check for certain value if it exists in a mysql database. If the value does not exists, it would simply add the value and refresh the page once to load the page again and now it has a value in the database, would go ahead to add other values. How do I refresh page just once when it is called ?
<?php
$sname = "W3 schools C# tutorials";//$_POST["sitename"];
$stype = "C#";//$_POST["sitetype"];
$saddy = "www.w3schools.com";//$_POST["siteaddress"];
$scomm = "W3 schools C# tutorials";//$_POST["sitecomment"];
$conn = mysql_connect("localhost","root","password");
if(!$conn){
die("Could not connect: ".mysql_error());
} else {
mysql_select_db("bookmarks",$conn);
$rs = mysql_query("select TypeId from bookmarktypes where TypeName = '$stype'");
$row = mysql_fetch_array($rs);
if($row > 0 ){
//Data found, continue to add...
} else {
//No data... insert a valid one
$rs = mysql_query("insert into bookmarktypes (TypeName) values ('$stype')");
if (!$rs){
die('Error: ' . mysql_error());
} else {
//echo "inserted new type data...";
}
//echo "</html>";
}
}
mysql_close($conn);
//Refresh page once
?>
There's the comment to refresh page below after mysql close command.
Refresh it right after insert with
header('Location: url here');
exit;
Btw, read a little about sql injections
Also - mysql_close() is pointless there.
if(check=1)
{
echo "\"<meta http-equiv=\"refresh\" content=\"2;url=http://yourwebsite.com/\">\"\n";
}
if you need to print the data that you just have entered try this
header('Location: YourShowDataPage.php?id='.$_POST['id_dataEntered'])
mi apologizes if is wrong , im a begginer
